General question : which units do you use to take cities ?
A tank cost 375 and have a strength of 34 against cities (50 base -33%), and use lot's of material to reinforce.
An infantry cost 240 , have a strength of 43 against cities (36 base +20%), can get another +20% city promotion and use almost no material.
Not counting the defensive bonus on rough terrain to keep your ground, in fact you should build tanks only to keep enemy infantry far away of your cities
But I'll like more feedback on that point.
